I am looking at the Fairchild FAN7382 half bridge gate driver. On page 2 of their data sheet (attached) they show a typical application circuit. In this diagram, there is a resistor R2 from the gate of Q1 (the high side MOSFET) to the source of Q1. Similarly, there is a resistor R4 from the gate of Q2 (the low side MOSFET) to the source of Q2.
What is the purpose of these resistors? Are there any rules of thumb for determining values to use for these?
